The ip-interfaces library provides a convenient way to obtain a list of available interfaces on a machine.
IP-Interfaces is a port of Clozure CL's %get-ip-interfaces function to CFFI so that it can run on other lisp implementations. So far ip-interfaces has been tested successfully on the following platforms:
| Implementation | Windows | Mac OS X | Linux | OpenBSD |
|---|---|---|---|---|
| SBCL | Yes | Yes | Yes | Yes |
| CLISP | Yes | Yes | Yes | |
| Clozure | Yes | Yes | ||
| Allegro | Yes | Yes | ||
| ECL | Yes | Yes | ||
| LispWorks | Yes |
IP-Interfaces is released under the LLGPL to maintain license compatibility with Clozure CL.
Note: ip-interfaces is not a socket library. If you are looking for a portable socket library, check out usocket.
The API for ip-interfaces consists of a single function, get-ip-interfaces, which returns a list of ip-interface structs containing information about the interfaces on the machine:
* (ql:quickload :ip-interfaces)
NIL
* (use-package :ip-interfaces)
T
* (get-ip-interfaces)
(#S(IP-INTERFACES::IP-INTERFACE
:NAME "lo0"
:ADDRESS #(127 0 0 1)
:NETMASK #(255 0 0 0)
:BROADCAST-ADDRESS #(127 0 0 1)
:FLAGS 32841
:ADDRESS-FAMILY :AF-INET)
...)
* (ip-interface-address (first *))
#(127 0 0 1)
